Description

Technical Field

[0001] This invention relates to the field of pipeline laying technology, and in particular to a pipeline laying device and method for building engineering. Background Technology

[0002] Fire protection pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials, and to transport fire-fighting water, gas or other media.

[0003] Chinese patent CN221522066U discloses an auxiliary device for laying fire protection pipelines in building engineering. By using a lifting rod, a sector block can be moved upward to loosen the locking nut. By using the cooperation of the rotating shaft and the sector block, the support block can be rotated, turning the telescopic rod to a vertical position. With the use of the fixing component, the pipeline on the fixing component can be erected, thereby facilitating the vertical installation of fire protection pipelines and improving the applicability of this device.

[0004] The aforementioned device can erect and install pipes through the cooperation of telescopic rods and fixed components, but it still requires the assistance of staff during operation, which is inconvenient. If hydraulic rods or electric push rods are used to drive the pipes to deflect, the pipes can only be adjusted in angle during installation, and the installation position of the pipes cannot be adjusted in the vertical direction, making the overall practicality of the device insufficient.

[0005] Therefore, it is necessary to provide a pipe laying device and laying method for building engineering to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a pipe laying device and method for building engineering, in order to solve the problem mentioned in the background art that the existing devices use hydraulic rods or electric push rods to drive the pipe to deflect, and the pipe can only be adjusted in angle during installation, but cannot be adjusted in the vertical direction to adjust the installation position of the pipe.

[0007] Based on the above ideas, the present invention provides the following technical solution: a pipe laying device for building engineering, including two sets of support plates and a scissor lifting mechanism set on the top of the support plates. The scissor lifting mechanism is driven to lift by an external drive component. A connecting rod is provided between the two sets of scissor lifting mechanisms. The output end of the drive component is hinged to the connecting rod on one side of the bottom of the scissor lifting mechanism.

[0008] The bottom of the scissor lift mechanism is provided with a base and a slider at both ends. The slider slides in cooperation with the guide rail on the support plate. The two connecting rods at the bottom are respectively rotatably engaged with the base and the slider. An upper stop bar is provided above the guide rail. An adjusting rod that cooperates with the upper stop bar is installed on the slider. The upper stop bar is provided with a slot. When the adjusting rod moves to the slot, the adjusting rod can be extended from the slot, so that the scissor lift mechanism can rotate about the connecting rod at the base as an axis.

[0009] As a further aspect of the present invention: a guide shaft is provided between the base and the slider. The guide shaft passes through the connecting rod on the base and is fixedly engaged with the connecting rod. The guide shaft also passes through the slider and engages with the slider through a snap-fit ​​assembly. The adjusting rod and the slider are elastically engaged. When the adjusting rod moves to the slot and springs upward, the slider can lock with the guide shaft.

[0010] As a further aspect of the present invention: the snap-fit ​​assembly includes a snap-fit ​​strip, which is slidably mounted on the slider, and the outer circumferential surface of the guide shaft is provided with a snap-fit ​​groove that cooperates with the snap-fit ​​strip.

[0011] As a further embodiment of the present invention: a rotating bracket is installed on the slider, and the center of the rotating bracket is rotatably engaged with the slider through a circular shaft; a guide post is provided on the adjusting rod; a protrusion is provided on the clip; and a guide groove is provided on the rotating bracket to slide and engage with the guide post and the protrusion.

[0012] As a further aspect of the present invention: the top of the support plate is provided with a guide groove that slides with the base, and the base is provided through the guide groove and can slide relative to the support plate along its length direction.

[0013] As a further aspect of the present invention, the base and the support plate are elastically connected.

[0014] As a further aspect of the present invention: the top of the scissor lifting mechanism is provided with a support platform for placing pipe fittings.

[0015] As a further embodiment of the present invention: a pressure plate that cooperates with the pipe fitting is hinged on the support platform. One end of the pressure plate is hinged to the support platform, and the other end of the pressure plate is fastened to the outside of the pipe fitting and locked to the support platform.

[0016] As a further aspect of the present invention: a stop block is slidably connected to the upper stop bar, and the stop block is used to seal the groove.

[0017] A method for laying pipes using the above-mentioned pipe laying device for building engineering includes the following steps: placing the pipe fitting above the scissor lift mechanism, using a drive assembly to unfold the scissor lift mechanism to adjust the installation position of the pipe fitting in the vertical direction; when the adjusting rod moves to the slot, the drive assembly can push the scissor lift mechanism to rotate about the connecting rod at the base as an axis to adjust the installation angle of the pipe fitting.

[0018] Compared with the prior art, the beneficial effects of the present invention are: this device can not only drive the scissor lifting mechanism to unfold or fold to adjust the installation position of the pipe in the vertical direction through a single drive component, but also drive the scissor lifting mechanism to rotate around the connecting rod on the base as an axis, thereby adjusting the installation angle of the pipe and adapting to different installation states of the pipe.

[0030] like Figures 1-9 As shown, a pipe laying device for building engineering includes a frame 1 and support plates 10 fixed to both sides of the top of the frame 1. The support plates 10 are provided with a scissor lifting mechanism 2 for lifting pipe fittings 5. The scissor lifting mechanism 2 is driven to lift by an external drive component 7. This structure is conducive to lifting the pipe fittings 5 ​​to a high position, thereby facilitating the installation of the pipe fittings 5 ​​at a higher position.

[0031] The scissor lift mechanism 2 mainly includes multiple sets of cross-arranged connecting rods. The middle parts of two adjacent connecting rods in the front-to-back direction are hinged by a pin, while the ends of two adjacent sets of cross-arranged connecting rods in the vertical direction are hinged by a connecting rod 4. The connecting rod 4 is arranged between two sets of scissor lift mechanisms 2 and passes through the end of the connecting rod. The connecting rod 4 and the connecting rod can be rotated together by a bearing. The drive assembly 7 is hinged to the bottommost connecting rod 4, thereby driving the scissor lift mechanism 2 to unfold or fold.

[0032] Furthermore, the bottom ends of the scissor lift mechanism 2 are respectively provided with a base 12 and a slider 9. The support plate 10 is fixedly installed with a guide rail 6 that slides with the slider 9. The base 12 is connected to the support plate 10. The connecting rod 4 located at the bottom layer and away from the drive component 7 passes through the base 12 and rotates with it. The connecting rod 4 located near the drive component 7 and at the bottom layer rotates with the slider 9. With this structure, when the drive component 7 pushes the slider 9 to slide along the guide rail 6 through the connecting rod 4, the scissor lift mechanism 2 can be unfolded or folded, thereby adjusting the position of the pipe 5 in the vertical direction, which is beneficial for the installation of the pipe 5.

[0033] While the above structure allows adjustment of the vertical position of pipe 5, it makes it difficult to adjust the angle of pipe 5. When it is necessary to tilt or arrange pipe 5 longitudinally, the above structure becomes limited in use. Therefore, this solution includes an upper stop bar 8 above the guide rail 6, as shown in the reference... Figure 4As shown, the slider 9 is equipped with an adjusting rod 15 that cooperates with the upper stop bar 8. Specifically, the guide rail 6 can limit the slider 9 in the horizontal direction, and the adjusting rod 15 and the upper stop bar 8 can limit the slider 9 in the vertical direction, so that the drive assembly 7 can stably push the slider 9 to move along the guide rail 6.

[0034] Furthermore, the upper stop bar 8 is provided with a slot 801. When the adjusting rod 15 moves to the slot 801, the adjusting rod 15 can move upward from the slot 801, so that the scissor lifting mechanism 2 can rotate about the connecting rod 4 at the base 12 as an axis, thereby adjusting the installation angle of the pipe fitting 5, specifically as follows: Figure 9 As shown.

[0035] When the scissor lift mechanism 2 deflects at a certain angle about the connecting rod 4 on the base 12, in order to maintain the stability of the scissor lift mechanism 2, this solution provides a guide shaft 11 between the base 12 and the slider 9. Specifically, the guide shaft 11 passes through the connecting rod 4 at the base 12 and is fixedly engaged with the connecting rod 4. The guide shaft 11 also passes through the slider 9 and is engaged with the slider 9 through a snap-fit ​​assembly. In this embodiment, the adjusting rod 15 is elastically engaged with the slider 9, and the adjusting rod 15 can move vertically relative to the slider 9. When the adjusting rod 15 moves to the slot 801 and springs upward, the slider 9 can lock with the guide shaft 11, thereby preventing relative movement between the slider 9 and the base 12, thus maintaining the stability of the scissor lift mechanism 2. Furthermore, when the slider 9 is locked with the guide shaft 11, the drive assembly 7 can push the end of the scissor lift mechanism 2 near the slider 9 upward during operation, thereby changing the installation angle of the pipe fitting 5.

[0036] In summary, this device, through a single drive component 7, can not only drive the scissor lifting mechanism 2 to unfold or fold to adjust the installation position of the pipe fitting 5 in the vertical direction, but also drive the scissor lifting mechanism 2 to rotate around the connecting rod 4 on the base 12 as an axis, thereby adjusting the installation angle of the pipe fitting 5 and adapting to different installation states of the pipe fitting 5.

[0037] Combination Figures 3-8 As shown, the snap-fit ​​assembly includes a snap-fit ​​strip 18, which is slidably mounted on the slider 9 and can move vertically relative to the slider 9. The outer circumferential surface of the guide shaft 11 is recessed inward to form an annular groove 1101 that cooperates with the snap-fit ​​strip 18. When the snap-fit ​​strip 18 moves downward and is inserted into the groove 1101, the slider 9 and the guide shaft 11 are locked together.

[0038] The slider 9 is provided with a mounting groove for accommodating the rotating bracket 17. The center of the rotating bracket 17 is rotatably mounted in the mounting groove via a circular shaft. The adjusting rod 15 is provided with a guide post 1501 that cooperates with the rotating bracket 17. During the up-and-down movement of the adjusting rod 15 relative to the slider 9, the guide post 1501 can cause the rotating bracket 17 to deflect around the circular shaft. The locking strip 18 is provided with a protrusion 1801 that cooperates with the rotating bracket 17, so that during the deflection of the rotating bracket 17, the locking strip 18 can be driven to move in the vertical direction relative to the slider 9.

[0039] In summary, during use, the pipe fitting 5 to be installed is placed on the top of the scissor lifting mechanism 2. The drive assembly 7 pushes the connecting rod 4, which cooperates with the slider 9, thereby causing the slider 9 to slide along the guide rail 6 to unfold the scissor lifting mechanism 2. This facilitates the adjustment of the installation height of the pipe fitting 5. The slot 801 is blocked by the stop block 16. When it is necessary to adjust the installation angle of the pipe fitting 5, the stop block 16 can be pushed outward relative to the upper stop bar 8 to open the slot 801. At this time, when the adjusting rod 15 on the slider 9 moves to the slot 801, it can spring upward, thereby driving the rotating bracket 17 through the guide column 1501. The end near the adjusting rod 15 is deflected upwards. Through the cooperation of the rotating bracket 17 and the protrusion 1801, the locking strip 18 can be moved downwards. When the bottom end of the locking strip 18 is inserted into the slot 1101, the slider 9 and the guide shaft 11 are locked, so that the bottom two ends of the scissor lifting mechanism 2 are locked. At this time, the scissor lifting mechanism 2 cannot be extended or retracted. As the driving component 7 runs, it can drive the scissor lifting mechanism 2 to rotate around the connecting rod 4 at the base 12 as the axis, so that the angle of the pipe 5 can be adjusted, so that the pipe 5 can be installed in an inclined or vertical state, which is beneficial to improving the overall practicality of the device.

[0040] In actual use, to unlock the scissor lift mechanism 2, this design provides a guide groove 1001 on the top of the support plate 10 that slides with the base 12. The base 12 passes through the guide groove 1001 and can slide relative to the support plate 10 along its length. Furthermore, the base 12 can be elastically connected to the support plate 10. In actual use, after the pipe fitting 5 is installed, the telescopic end of the drive assembly 7 retracts, and the scissor lift mechanism 2 can deflect downwards about the connecting rod 4 at the base 12. When the slider 9 falls onto the guide rail 6, the telescopic end of the drive assembly 7 retracts. During the process, the entire scissor lifting mechanism 2 can be pulled. At this time, the base 12 slides in the guide groove 1001. When the adjusting rod 15 is pressed and moves to the bottom of the upper stop bar 8, the downwardly pressed adjusting rod 15 can drive the rotating bracket 17 to deflect upward near the protrusion 1801, thereby driving the locking bar 18 to move upward and disengage from the locking groove 1101, so that the bottom two ends of the scissor lifting mechanism 2 can move relative to each other. Therefore, in this way, there is no need to set up additional parts to unlock the locking block and the locking groove 1101, making the device operation more convenient and the operation more stable.

[0041] like Figure 1 As shown, the top of the scissor lift mechanism 2 is provided with a support platform 3 for placing the pipe fitting 5. The top of the support platform 3 is set as an arc surface. A pressure plate 301 that fits with the pipe fitting 5 is hinged on the support platform 3. Specifically, one end of the pressure plate 301 is hinged to the support platform 3, and the other end of the pressure plate 301 is fastened to the outside of the pipe fitting 5 and can be locked to the support platform 3 by bolts or fasteners, which helps to maintain the stability of the pipe fitting 5 on the support platform 3. The two connecting rods 4 located at the top of the scissor lift mechanism 2 are each rotatably fitted with retaining rings, and T-shaped positioning blocks 13 are fixedly set on the retaining rings. Figure 3 As shown, the positioning block 13 on one of the retaining rings slides into the T-slot at the bottom of the support platform 3, while the positioning block 13 on the other retaining ring is fixedly connected to the support platform 3.

[0042] Combined again Figure 1 As shown, the drive assembly 7 can be an electric push rod or a hydraulic rod, etc., and a support frame for mounting the drive assembly 7 is welded on the frame 1. The tail end of the electric push rod or hydraulic rod is hinged to the support frame, while the telescopic end of the electric push rod or hydraulic rod is hinged to the connecting rod 4. Figure 1 As can be seen, the tail end of the drive component 7 extends below the bottom of the support plate 10, which is beneficial for the drive component 7 to push the scissor lifting mechanism 2 to unfold or to push the scissor lifting mechanism 2 to deflect as a whole.

[0043] The outer side of the upper stop bar 8 is fixedly connected to the guide rail 6 or the support plate 10 by a support rod.

[0044] Combination Figures 3-4 As shown, longitudinal rollers are rotatably mounted on both sides of the base 12, and the longitudinal rollers are located at the top and bottom of the support plate 10 to limit the vertical displacement of the base 12. A transverse roller is rotatably mounted on the base 12 at a position inside the guide groove 1001 to limit the displacement of the base 12 along the width direction of the support plate 10, so that the base 12 can only slide stably along the length direction of the support plate 10. An elastic telescopic rod is fixedly provided between the side of the base 12 near the slider 9 and the inner wall of the guide groove 1001 to achieve elastic cooperation between the base 12 and the support plate 10.

[0045] Combination Figure 6 As shown, the guide shaft 11 passes through a pre-set through hole on the slider 9, and the bottom end of the locking strip 18 extends to the through hole and can cooperate with the locking groove 1101 on the guide shaft 11. The rotating bracket 17 is provided with a guide groove 1701 that slides and cooperates with the protrusion 1801 and the guide post 1501, so that the locking strip 18 can move vertically during the up and down movement of the adjusting rod 15. An elastic telescopic component 19 is fixedly installed between the horizontal section of the adjusting rod 15 and the top of the slider 9. Specifically, the elastic telescopic component 19 includes a telescopic rod and a limiting spring sleeved on the outside of the telescopic rod. A convex shaft 14 is fixedly provided at the end of the horizontal section of the adjusting rod 15. The convex shaft 14 can be made of plastic, hard rubber or metal, and the top end of the convex shaft 14 is a spherical or conical structure. When the drive component 7 pulls the entire scissor lifting mechanism 2 to move, the squeezing force between the spherical or conical surface on the convex shaft 14 and the bottom of the upper stop bar 8 can drive the convex shaft 14 to move downward, thereby driving the adjusting rod 15 to move downward.

[0046] Combination Figure 7 As shown, the block 16 is generally L-shaped, and a horizontal shaft is fixedly provided on the outer side of the upper baffle 8. The horizontal shaft passes through the vertical section of the block 16 and slides with it. Through this structure, the position of the block 16 can be adjusted to achieve the blocking state or the opening state of the slot 801.

[0047] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
